SpringBoot整合RabbitMQ

RabbitMQ是開源消息隊列系統，用erlang語言開發。若是不瞭解能夠查看官網http://www.rabbitmq.com/

這篇文章介紹一個springboot簡單整合RabbitMQ。

1.安裝rabbitmq，自行百度便可，方法不少。

2.啓動rabbitmq，成功以下圖：

能夠訪問http://localhost:15672/查看管理頁面

新建項目，pom文件加入依賴，完整pom以下：

            </plugin>
        </plugins>
    </build>


</project>

新建一個消息發送者Sender，使用AmqpTemplate將消息發送到消息隊列message中去。代碼以下：

package com.dalaoyang.sender;

import org.apache.log4j.Logger;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.send
 * @email yangyang@dalaoyang.cn
 * @date 2018/4/25
 */
@Component
public class Sender {
    Logger logger = Logger.getLogger(Sender.class);

    @Autowired
    private AmqpTemplate amqpTemplate;

    public String send(){
        String context = "簡單消息發送";
        logger.info("簡單消息發送時間："+new Date());
        amqpTemplate.convertAndSend("message", context);
        return "發送成功";
    }
}

建立消息接收者Receiver，使用註解@RabbitListener(queues = "message")來監聽message的消息隊列@RabbitHandler來實現具體消費。

package com.dalaoyang.receiver;

import org.apache.log4j.Logger;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.receiver
 * @email yangyang@dalaoyang.cn
 * @date 2018/4/25
 */
@Component
@RabbitListener(queues = "message")
public class Receiver {
    Logger logger = Logger.getLogger(Receiver.class);

    @RabbitHandler
    public void process(String Str) {
        logger.info("接收消息："+Str);
        logger.info("接收消息時間："+new Date());
    }
}

而後看一下配置信息，由於是簡單整合，因此只配置了端口和rabbitmq的信息，以下：

##端口號
server.port=8888

##rabbitmq
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

建立一個controller，這裏僅用來測試，代碼以下：

package com.dalaoyang.controller;

import com.dalaoyang.sender.Sender;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.controller
 * @email yangyang@dalaoyang.cn
 * @date 2018/4/25
 */
@RestController
public class TestController {

    @Autowired
    private Sender sender;

    @GetMapping("hello")
    public String helloTest(){
        sender.send();
        return "success";
    }

}

啓動項目，訪問http://localhost:8888/hello而後觀看控制檯能夠看到消息已經發送成功。
